Filed: 1982-07-13
Abstract: PURPOSE:To carry out extracting operation in an org. extractant system in good efficiency, by stably holding the dispersing phase in the mixer of an mixer settler type extractor. CONSTITUTION:1wt% aqueous acetic acid solution containing 0.1wt%, of a solid is delivered in a mixer (m) from a pipeline 1 at a speed of 5.3l/hr and a org. solvent containing tertiary amine is delivered therein from a pipeline 2 at a speed of 9l/hr. Subsequently, a mixed liquid having the solvent dispersed therein prepard in the mixer (m) is sent to a settler (s) from a pipeline 4 to disperse the org. solvent phase (o) in a water phase (w). In addition, the amount of the water phase again returned to the mixer (m) in the water phase discharged from the pipeline 6 of the settler (s) is adjusted to 8l/hr to be returned from a pipeline 3. As the result, when continuous operation is carried out for one month, a phenomenon such that the dispersion phase comes to a water phase is not generated at all while the dispersion state in the settler (s) is well and the org. solvent phase can be taken out from a pipeline 5.

Filed: 1996-04-19
Abstract: PROBLEM TO BE SOLVED: To increase speed in designation of an address of a display element and writing-in and reading-out of data by shortening disappearing time of a gas mixture in a flat panel display system or a memory system using an ionizable gas mixture. SOLUTION: A gas mixture is obtained by mixing an ionizable gas medium and gas containing ionizable particles whore energy level is matched according to collision. Ionizable gas is put still in an ionized condition by an ionizing means, and in an excited condition where ionizable particles matched by collision collide with each other, Atomic particles of ionizable gas are generated. Therefore, in a condition where collision of ion atomic particles is metastable, the number of collision times between the atomic particles of ionizable gas is reduced, and time necessary for the ionizable gas to return to a nonionizing condition from an ionized condition is shortened.

Title: Resistance welding method
Inventor: FURUKAWA TAKATSUGU
IPC: B23K11/10
Filed: 1978-10-06
Abstract: PURPOSE: To prevent the annihilation, discoloration and dent of hairlines by performing pressure  current supply in the state where only the periphery of the mutual contact pressure parts of the  materials to be welded are supported by pressure electrodes.   
     CONSTITUTION: A protrusion 14 is provided to the material 1 to be welded which does not require aesthetic appearance and with said protrusion being faced to the side of the material 2 to be  welded where there are no hairlines, the materials are held between electrode chips 3, 4. The leading end of the electrode chip 4 has a recess 5 encircled by the conical inside wall 8 of the cover 12  protruding from this and the bottom face 2' of the material to be welded. The recess 5 is disposed  right under the weld zone 15 and the pressing forces of both electrode chips are received by the  rigidity of the material 2 to be welded per se. Hence, the weld zone 15 deforms and when current  is supplied next, the contact parts of the materials to be welded weld and the foregoing deformation returns as much as this. When the current supply is stopped, the face 2' returns flat owing to  the thermal shrinkage of the nugget 10 and the pressed part 9 detaches from the weld zone 14.  Since the pressure receiving area is wide, the hairlines are not crushed. On the other hand, when  gas is flowed from inlet 7 to the recess 5, the weld zone is surely covered with the gas, whereby  its discoloration is prevented.
